Mach head units don't use RCA preouts, you have a line out converter somewhere. 90% of people run them off a rear channel. Usually they splice into the speaker wire right around the rear deck, I have seen some people splice in up by the headunit as well, rare, but it happens.

Your converter could have went out, if you have no sound out of the speakers as well there is a possiblity you have a problem with a Mach amp, or the power/signal going to it. There are a couple hundred things that could be wrong. Thing that really sucks is that you could just have a wire grounding out somewhere, and factory wiring is all bunched and loomed together.

we need a list of what is in the car before we can make an educated guess as to what could be wrong.  Model numbers and how they are wired, not color shape or anything else.

i wouldnt buy anything just yet. chances are its just the fuse in your engine bay coming from your battery. take the time on a nice day when you've got some time on your hands to gut and re-install your system. guarantee you'll make it 20% through and you'll figure out what the problem was. this is a good oppurtunity to go and hide all the wires and solder/shrink tube any loose connections, zip tie bundles etc.

have a friend help you out and it'll go quickly and painlessly
